movement and providing'for lateral detiec tien of the several connected.

The particular object of the invention is to provide a constructionwhereby the edge of one pile will. be Vengaged by the other'l to pilesof a. series when "provide a strong flexible joint., preventingI thespreading' of the holding elements and counter-acting the variousstrains to which constructions'r of this class are subjected in use; andespecially to provide a construcion wherein interlocking engagement ismaintained by (Jo-acting hook elements and embracing elementsrespectively, of adjacent piles.

f Heretofore in steel piling wherein one oi the edges is engaged withinor between the embracing edges of the next adjacent pile, strainstending to separate the piles have caused the said elements to open orspread, and one of the objects of my invention is to so construct thepilesas to pro-.

vide l'ieariizf.;` edges which are so arranged as to oppose spreadingstrains at the `mirious I uns which the piles may assume with relationto each other.

The present invention embodies improvements over that shown in my priorapplicaion filed September 9th, 1908, Serial No. maar. Y

in the drawings accompanying the specification: Figure l is a crosssectional view .showing a plurality of piles assembled, each beingprovided with 'interlocking terminal edges cti-acting with theappropriate edges of adjacent similar piles. Fig-2 is a similar viewshowing an ampliiication of the construction of l. v

Generally stated, each pile consists or a icngitudinal web portion 2having boundary edges arranged to telescopieally interit and tio-actwith the edges of adjoining piles. n

the construction shown in Fig. 1 the web 2 is provided at one of itsedges with enlargements 3, 4f, partly cylindrical in form, both insideand out, having gradually reduced tapering body portions roundingoutwardly at each side and toward their terminals 5, 6. As shown, one ofsaid terminals l5 gradually tapers to its rounded terminal edge withoutsubstantial 'variation of the inner and 'outer cylindrical curvature,while the ther terminal (i is similarly tapered but is abruptlydellected inwardly, beyond an intervening receiving` cavity, .so as to,provide a retaining longitudinal edge flange forengagement with theterminal edge of -a coaeting pile coifistructed as is the other edge atthe lett side of Web 2. Said edge vof such co-acting pile or of the.otherside of 'the same pile, terminates in a tapering rearwardlydeflected retaining longitudinal edge flange 7, with a similarintervening rcavity adapted to snugly receive the terminal edge (5, anda rounded body portion 8 at one side adapted to bear against embracingterminal portion 5. -The other side of suchedge portion'ot theinter-fitting pile is bulbously extended as at 9, to embrace or 'partlyembrace the outer rounded portion of terminal 6, as will be readilyunderstood. The coacting hook terminals 6 and 7 are preferably locatedsubstantially in alinernent with the web 2 of the pile, or approximately'so and suliiciently olii-set therefrom, so that When engaging eachother as shown, the separating strain will be counteracted approximatelyin the plane of the webs when in alinement or substantially at themiddle portion of-the jointin any position. As thus constructed it willbe seen that the hooked elements of the adjacent edges of connectedpiles will interfit with each other;

that ample space is provided inwardly .be-

parts in rigid engagement when set, While permitting liexibility oraejustnient and insuring practically 'Watertight joint throughout.

In Fig. 2 I tion of the construction shown in Fig. l, in Whichl theinterlocking piles are of substantially the same cross section, beingmerely made in riv'ht and left hand forms at the respective edges of thepile. 'In such construction the Web 2 is provided at each of its edgesWith dividedenlargements 3, Il', partly cylindrical in forni havinggradu-- allyl reduced tapering body portions rounded outwardly at eachside and toward the terminals 5', 6. 'As shown one of said terminals 5gradually tapersA to its rounded terminal edge Without substantialvariation of the inner' and outer cylindrical curvature, While the otherterminal 6 is similarly tapered but is abruptly deflected inwardly sc asto provide a retaining'.longitudinal edge' iiange for engagement Withthe corresponding edge liange of a co-acting pile of similar Storm. Asthus constructed and in- 'terfitted'it Will be seen that the hookedele'- 'ments of the adjacent edges of connected piles Will interlit Witheach other in the' same general manner -as has been described as to theconstruct-ion oi' `Fig. l and that the embracing termina-ls 5 at `leachside Will maintain the parts vin braced engagement,

counteracting any strains tending to open up or separate the operatingparts, While.

providing uniformity olf construction of the -pile at each edge, andpermitting the piles to be interchangeably inserted at either end.

WT ith either construction it will be seen that, due to the inwardlyturned terminals and outer bracingporti'ons oi the engaging edges, theinterfitting holding elements will be rigidly retained under pullingstrains at Whatever'A position the parts may assume. Also that theinteriitting hooked terminals 'and 7 or 6 and 6 will be inclosed Withinthe receiving cavities of the other pile, pro

viding rounded bearing faces at all posh' tions and eiiicientlyperforming the fund' tions intended.

The. pilee are of simple construction; they may bev readily rolledinpropcrly designed rolls, either entirely, or partly by rolls-and theninished by suitable dies or other niachincry.v The Adisposition of themetal is such as to secure the best results While the prevention ofjoints will be Wound to avoid the common have illustrated anamplicaspreading or opening oi the' nacer l.
